PAPER-WINDER.

Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed. September 6, 1910. Serial No. 580,566.

To all whom it may concern:

Be it known that I, ARTHUR GAUTHIER, a subject of the King of England,residing at Portneuf Station, in the Province of Quebec, Canada, haveinvented certain new and useful Improvements in Paper-VVinders; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention to be hereinafter described relates to paper windingmachines.

Broadly speaking, it comprises a framework adapted to support theseveral working parts, guide and pressure rolls mounted within theframework, supports swingingly expansible paper receiving rolladjustably mounted in the supports, means for expanding the paperreceiving roll, means for adjusting opposite ends of the paper receivingroll to level it, means for raising the supports vertically, and meansfor swinging the supports to a position to remove the filled receivingrolls.

In order to more clearly disclose the construction, operation, and useof the invention, reference should be had to the accompanying drawingsforming part of the pres ent application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings: Figure 1 is a side elevation of the invention,complete; Fig. 2 is a plan view of Fig. 1; Fig. 3 is a verticallongitudinal cross section on line 33 of Fig. 1, looking in thedirection of the arrows; Fig. 1 is an enlarged, fragmentary detail ofthe mechanism for adjusting one end of the paper receiving roll; Fig. 5is a left hand side elevation of Fig. 4; Fig. 6 is a fragmentarysectionalview of one end of the paper receiving roll; Fig. 7 is avertical cross section on line, 7 7 of Fig. 6, looking in the directionof the arrow; and Fig. 8 is a side elevation of the pawl and ratchetmechanism forming part of the support raising, mechanism.

Referring to the drawings in detail, 1 indicates a framework in whichthe several working parts are suitably mounted. Mounted in thisframework and extending laterally across the same from side to side, isa large guide roll 2 of considerable diameter. In rolling, the paperstrip X passes about the under and rear surface of this roll and iswound upon the receivingroll 3. The receiving roll is mounted inbearings extending outwardly from guides 4 slidably mounted on theI-beam supports 5. These guides are each provided with an arm 6 having ascrew threaded bore and adapted to move freely in the opening 7 of itssupport. A threaded rod 8 is revolubly journaled in the upper end ofeach support and cooperates with the threaded bore of each ear. The rod,of course, is provided with suitable removable stop collars 9 to preventany longitudinal movement. Rotation of the rod 8 may be effected by thecrank handle 10. By turning the rods 8, the ends of the receiving rollmay be raised or lowered, as desired; for slight adjustments. WVhen theroll has been filled, its removal is desirable. For this purpose, theupper half 11 of the bearing 12 is hinged to its guide 4 so thatit maybe swung upward to permit removal and return of theroller. When the rollis in position, a spring pressed pin 13,

passed through openings in the outer ends of the upper and lower halvesof the bearing, holds it in operative position.

The paper should be wound tightly and closely on the roll 3 in order toget the best results. For this purpose, an adjustable pressure roll 14is provided. The ends of this roll are journaled in blocks or bearingsadapted to slide freely in guides 15 extending longitudinally of theframe. The roll 14 is slightly below the receiving roll 3. Consequently,by sliding the roll 14 in one direction or the other in its bearings, itmay be made to approach or recede from the surface of the receiving roll3, thereby regulating the amount of pressure it exerts on the paper ofthe receiving roll. In order to adjust the pressure roll, rack andsegment gears are provided. The segment gears 16are fixed to oppositeends of a shaft 17 which is journaled in the framework beneath theguides 15. These gears each mesh with and operate a toothed rack 18depending from the under face of each bearing of the roll 14. The shaft17 may be operated by means of a lever handle 19 fixed thereto. Thehandle is provided with the usual spring catch 20 adapted to cooperatewith the notched are plate 21 to hold the roll in its various adjustedpositions.

The weight of the roll 3 audits paper,

bearing upon the drum 2 and pressure roll 14, provide suflicientfriction to enable the roll 3 to be driven from the drum 2. Therefore,it is only necessary to drive drum 2 in order to operate the receivingroll 3.

The supports 5 are slidably mounted in casings 22 pivotally suspendedfrom the ends of a shaft 23 which is journaled in the framework 1. Inorder to guide the supports accurately in their vertical movements,several pairs of guide rollers 24 are provided. These rollers arearranged to fit into the channels of the supports and engage the wallsor edges thereof, as shown in Fig. 3. Several pairs of rollers areprovided for each support. The rollers on each side are exactly alined,of course. They are, preferably, arranged so that the rollers on onesidewill fall directly opposite the rollers on the opposite side. Inthis way, a strong, efficient, and accurate guiding means is provided.

As the paper on the receiving roller 3 increases in thickness, theroller will be gradually forced upward, carrying the supports with it.

When the roll has received the required amount of paper and it isdesired to remove it, the supports will be raised vertically and swungrearwardly, as indicated in dot-ted lines in Fig. 1. In order to effectthe vertical raising, a pawl and ratchet mechanism and suitable gearinghave been provided. This comprises a hub 25 keyed to the shaft 23 andprovided with a ratchet 26 adapted to be engaged by the spring operatedpawls 27 pivotally mounted on a plate 28 secured to the center of asprocket wheel 29 freely revoluble on the shaft 23. Rotation of thesprocket wheel 29 in a counter-clock-wise direction causes engagement ofthe pawls 27 with the teeth of the ratchet 28, thereby rotating theshaft 23. To each end of the shaft 23 is secured, by a set screw or thelike a small pinion 30 which meshes with a rack 31 formed on the face ofeach support 5. Thus, rotation of the shaft 23, in a counter-clock-wisedirection, causes raising of the supports 5 and the roll 3. For drivingthe sprocketasprocket chain 32 has been provided. This sprocket chain isdriven from a small sprocket wheel 33 fixed to a stub shaft 34 journaledin one side of the frame 1. To the stub shaft 34 is also connected alarge gear wheel 35 which meshes with and is driven by a smaller gearwheel 36 fixed to the inner end of a second stub shaft 37 journaled in abearing mounted on the frame 1. The outer end of this stub shaft isprovided with a hand wheel 38 by which it may be operated. Rotation ofthe hand wheel, in the direction of the arrow, therefore, causes araising of the receiving roller 3. In order to stop the raisingmechanism at exactly the right point, a gear face 39 has been formed onthe gear 35 and a dog 40 has been mounted adjacent the gear face toengage the teeth and hold the gear 35 against rotation. One arm orbranch of the dog is extended considerably beyond the framework 1 andprovided with a treadle 41. Raising of the treadle efiects engagement ofthe gear teeth by the dog, in this way stopping the raising of theroller 3.

When the roller 3 has been raised to the dotted line position of Fig. 1,it is then necessary to swing it rearwardly in the direction of thearrows. To accomplish this, it is necessary to swing the casings 22through which the supports 5 slide. This is accomplished by means of aquadrant gear 42 formed on the disk or plate 43 which is detachablybolted or otherwise removably secured to the casing 22. Cotiperatingwith the quadrant gear is a worm 44 formed on a shaft 45 which isjournaled in suitable bearings mounted on the frame 1. A bevel gear 46is keyed to one end of the shaft 45 and adapted to intermesh with and bedriven by a similar gear 47 on a vertical shaft 48 mounted in bearingson the frame and provided with an operating hand wheel 49. Thus, byoperating the hand wheel 49, the supports 5 may be swung to move theroller 3 in the direction of the arrows of Fig. 1, so that the filledroller 3 may be removed and carted away.

The guide roll or drum 2 may be driven from any suitable source of powerand in the usual manner.

It may be desired to raise the supports by a more direct and somewhatquicker mechanism. To accomplish this, a hand Wheel 50 has been fixed toone end of the shaft 23. Rotation of this hand wheel, of course, effectsimmediate raising of the roller 3, therefore pinion 30 and rack 31.

It may be desired, for many reasons, to increase the diameter of thereceiving roller 3. For this reason, the roller may be made in twolongitudinal sections; a section 51 provided with hubs 52 adapted toreceive the ends of the roller axis 53, and a second sec- I tion 54fitting against the.first and provided 'with depending end pieces orplates 55 each having an elongated slot 56 adapted to freely receive aneccentric 57 fixed to the axis 53. The axis is adjustably mounted in thehubs 52 and provided with any suitable means for securing it in itsadjusted positions. By rotating the axis 53, in the hubs 52, theeccentrics 57 will engage the opposite walls of the slots 56 and soforce the section 54 toward or from the axis 53 and the section 51,thereby causing either expansion or contraction of the roller, asdesired.

It is thought that the operation and use of the invention will be clearfrom the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition ofthe several parts of the invention without in any way departing from thefield and scope of the same, and it is meant to include all such withinthis application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. A machine of the character described comprising a frame, a guideroller mounted therein, casings swingingly mounted on 0pposite sides ofsaid frame, supports slidably mounted in said casings, a receiving rollmounted on said supports, plates secured to said casings and providedwith segment gears, and worms meshing with said segment gears andadapted to drive the same to swingthe casings and their sup orts.
